The package offers enhancements for theorem-like environments:

• easier control of layout; proper placement of endmarks even when the environment ends with \end{enumerate} or \end{displaymath} (including support for amsmath displayed-equation environments); and
• support for making a list of theorems, analagous to \listoffigures.
